ABSTRACT:
A control circuit for a switched reluctance machine comprises a transistor connected with the machine winding across a rectified ac power supply. The transistor controls the flow of current through the winding in a primary current path. A silicon controlled rectifier and a capacitor are serially connected across the power supply and a diode is connected between the winding and the transistor and between the silicon controlled rectifier and the capacitor. In the steady state, the capacitor is charged each time the transistor is opened. The transistor and the silicon controlled rectifier are actuated together so that the capacitor discharges through the silicon controlled rectifier and the winding until the capacitor is discharged below the supply voltage. Thereafter, the silicon controlled rectifier ceases conduction and energy is drawn from the supply. The circuit avoids the need for a dc link capacitor across the power supply to smooth the supply voltage.
